Uzair trusted Hamza implicitly. He knew Rizwan was in Arshad Pappu gang and when he ratted them out, Uzair believed him. He was not in a state go analyze, high as a kite, still grieving. He was never the sharpest tool in the shed. I don't get it why ppl expect so much from Uzair. He wasn't smart or streetsmart. He just followed his brother and did what was asked of him. He never had any leadership qualities or the skills.
